Table limit
The table limit is the minimum and maximum bet that a gambler can make at a gaming table. It is a form of yield management in that the limits can be changed to optimize the profit from a gaming table. Gaming tables have a limited resource to sell, the seats used by the players.
Minimum table limits
Table limits can also be used to manage, in a limited manner, who plays at tables. A casino that wants to project a more exclusive image can set the limits higher so that the casual tourist walking through would not be as likely to sit down and play. Also games with a lower house edge often have a higher minimum bet. Baccarat almost always has a high minimum bet since the house edge is relatively low. Often a casino will advertise a low minimum game as a teaser, a sign might read $2 blackjack 24 hours a day. However, the $2 minimum game might be available at only one table and the payout might be 6:5 for a blackjack.
Historically the attitude has changed about table limits. In the early 1990s in downtown Vegas, quarter minimum bets were common. The low minimums created a general excitement in the casinos as hundreds of people would jostle to play table games. However, casinos floors generally had twice as many employees as they do today. It also made it much easier to introduce new gamblers to table games. Most casinos today would prefer that the low rollers play slot machines which do not require as much oversight.
